A novel molecular sieve supported Ag3PO4 was prepared for the first time.
Ag3PO4/SAPO-34 shows enhanced visible-light photocatalytic efficiency.
Ag3PO4 content in the composite strongly affects photocatalytic activity.
Depositing Ag3PO4 on SAPO-34 can reduce cost of Ag3PO4 photocatalyst.
Novel Ag3PO4/SAPO-34 increases the structural stability of Ag3PO4.
